This hose fitting is made of brass and has a 90-degree elbow shape for connecting hose to hose at an angle. This is for a fixed connection between plastic or rubber hose. Barbed fitting on both ends create a tight seal on flexible or semi-rigid hose when used with a hose clamp or crimp sleeve or ferrule (sold separately). This fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. The fitting has a temperature range of 32 to 200 degrees F.
